Changes for Web developers

HTML

Tables' {{ htmlattrxref("cellpadding", "table") }} attributes are now parsed the same outside quirks mode as they are in quirks mode. That is, if a value is specified as a percentage, it's treated as a number of pixels instead, since percentage values are not actually permitted according to the specification.

The {{ htmlelement("wbr") }} element has seen its bidirectional behavior fixed. It behaves now like the Unicode U+200B ZERO-WIDTH SPACE and therefore doesn't affect bi-directionality of its father anymore.

CSS

The turn {{ xref_cssangle() }} unit is now supported (to be used with CSS functions like rotate()).

Support for the CSS3 {{ cssxref("background-position") }} property extended syntax has been added. You can offset a background image from any corner by writing like "right 10px bottom 20px". See {{ bug("522607") }}

Support for the 2-value syntax of the CSS {{ cssxref("background-repeat") }} has been added.
